JOHN B. BRENNEN, OF ATLANTA, GEORGIA COTTON-CLEANER BEATER SHAFT Application filed January 21, 1929. Serial No. 334,000.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which t Figure 1 is a perspective view of a cotton cleaner with front portions broken away to show the beater shaft.

Figure 2 is an end view of the shaft.

Figure 3 is an end view of one of the 25 blades or heaters.

Figure 4 is a side view of one of the blades or heaters.

In the drawing, the letter A indicates the casing of the cleaner which is of ordinary or any desired construction, and the letter B indicates the heater shaft which is rotatably arranged in the casing in the usual manner. In carrying out my invention, I form the outer portion of each blade or heater 1 of the shaft with corrugations, as shown at 2,so that when these blades pass through the cotton, the corrugations tend to throw the cotton outwardly from the blade, whereas the flat blades, as now in use, tend to carry the cotton around 0 with them, as the cotton clings to these flat blades.

Operating tests with this corrugated type of blade proved that the corrugated blade is much more eflicient as an opening medium 5 than the flat blade.

What I claim is A heater shaft for a cotton cleaner having longitudinal rows of straight blades thereon, the outer end of each blade being corrugated, with the corrugations extending longitudinally'of the blade and said corrugations giving the blade a Zigzag shape in cross section.

JOHN B. BRENNEN.
